This genus may be distinguished from Platydema by its truncate intercoxal process 

 and short epipleurse. The mesosternum is less prominent, less deeply excavated than any 

 of the genera, except Alphitophagus. The thorax is narrower at base than the elytra, the 

 sides not rounded except in front, and gradually wider from apex to base. 



S. seneoluui, Lee (Nolit.es) loc. cit.; Lac, (Scaph.) Genera V, p. 804. 



As compared with the European species, this one is more; elongate, less rounded and 

 with a narrower thorax. 

 Length .14-18 inch, 

 from the Lake Superior region. 



HYPOPHLCEUS, Fab.

Easily known by its sub-cylindrical form, thicker antenna; and rather broader tibiee. 



The epipleuree are short.
